FIVIINERS LAMP.

Be it known-that 1, PETER S. .KEENAN, a

citizen of theUnited States, residing. at Kemmerer, in the county of Uinta and State of Wyoming, have invented new and useful Improvem'entsin'Miners Lamps,- of which the following is a specification.

I miners lamps and it consists of thenovel ro features of construction and combination of This invention relates to improvements in parts hereinafter fully described and claimed. 1 The object of the invention is to provide a I picking means and. an improved construc. 5

In the accompanying drawings, Figure 1 is aside elevation of a minerslamp embodyin my invention. Fig. 2 is a central vertica 1 front to rear sectionthrough the same. Fig. is a rear elevation. Fig. 4 is a top plan view with the cover thrown open. Fig. 5 is a detail view of the combined supporting device and pick.

. Referring to thedrawings, the numeral 1 designates the body or font of the'lam i I. which may be closed at top by any suitab efor'm of cover'2. Arranged at the front of thebody is a wick-tube 3, provided with an air-passage 4, extending axially or centrally through and communicatin at its lower end with an inlet 5, formed'in t e bottom of the font. 'The wick-tube communicates at its lower end with-the interior ofthe font, and

ranged therein about the passage 4, through i Preferably which latter. a current of'air is sup lied, at

the point of combustion to permit -t e wick tox'burn freely and to produce a clear and bright light. i

the upper end of the font and having their lower ends bent or curved outwardly, as. at

' 8, to provide flaring entrance and exit. pas+ sages between the same and font. The strips are spaced a art for the reception between the same of t e combined supporting device and pick hereinafter described, and adjacent their upper ends are outwardly offset to form keeper-loops 9. 1

,- The combined supportin device and pick comprises a stem 10, forme at its upper end into a hook 11 for supporting the lamp from the .miners cap, and having its lower end pointed, asat 12, to rovide a pick, whereby the wick may be piclfed or loosened and adjusted in the wick-tube when occasion requires, thus obviating the necessity of employing the primitive methods of accom lishing this result heretofore employed in am s unprovided with wick-raisin devices. T e

stem 10 is formed or provide with laterallyeXtending pins or lugs 13, adapted to engage the keeper-loops 9, whereby the supportin device and pick may be detachably secure to the lamp.

It will be understood that in detaching the supporting device the latter is forced downwardly, thus causing the pins 13 to press the spring-strip 7 outwardly. When said pins arrive at the flared portions 8, the supporting'. device maybe readily removed in an'ob- In applying the supporting device the latter' is p aced on a line between the strips 7 with t e pins 13 in the spaces between the lamp-body and bent ends 8 of the strip, and the supporting device is then drawn upwardly by means of the hook 11, the pins 13 riding upward between the strips and lam -body until they snap into the keepers 9, W en the supporting device will be securely held in position.

a It is thought that the st ructural features and advanta es of the invention will be fully om the foregoing description the metal also being folded to form a closed union between the Wick-tube and air-passage.

A minerslamp having a holder at the 15 rear thereof, com rising a pair of springstrips secured at 5161 1 upper ends and free from connection at their lower ends, said strips being spaced and bent to form keepers an a supporting device comprising a stem 20 having lugs to' ride between the lamp-body and strips and en age said keepers.
